Built in 1862, the so-called “Bas Col” battery was part of the defense system of the Southern Alps against neighboring Italy. Culminating at 2,505 meters, it monitored the Ubaye valley and the passage of the pass while serving as a relay for an optical transmission chain linking Grenoble to Toulon. The bends of the track provided for its access are so steep that at each turn it was necessary to unharness the horses, turn the hand cannons and re-harness!
